This time the popular commenting system has fallen victim to a massive security breach.

Disqus, the company which provides a web-based comment plugin for websites and blogs, has admitted that it was breached 5 years ago in July 2012 and hackers stole details of more than 17.5 million users.

The stolen data includes email addresses, usernames, sign-up dates, and last login dates in plain text for all 17.5 million users.

It is most likely that hackers could use this stolen information in tandem with social engineering techniques to gain further information on victims. So, you are advised to beware of spam and phishing emails carrying malicious file attachments.
